The Sunshine Aquarium is a small aquarium located on the roof of a nine-story building in Tokyo’s Sunshine City. On the roof, the open-air “Aqua Ring” is elevated about 7.5 feet off the ground, giving visitors an opportunity to view sea lions — and now penguins — swimming from beneath. (This video shoes sea lions swimming laps in the Aqua Ring.) The “flying penguin” exhibit currently runs from 6:30 and 7:30 PM, and it is expected to run through September 2, 2012.
